I have a question 
I have a 2.0 Supra (2023). Car is at around 30k miles now. Installed a JB+ last year (and >10/12k miles ago) and kept it at the "conservative" 3PM pot setting.
I use the car for long distance traveling (vacation, etc.) across Europe, and it has been running absolutely perfect.
You can feel a tiny bit more push with the JB+. I do not want to mess too much with the car, JB+ scratched a small itch, everything is peachy.
Now, I was recently bored and purchased a new OBD module that is compatible with BimmerCode/Link (the older one I used on my bikes wasn't) so I purchased BimmerLink as well.
I do the odd trackday here and there and I wanted to be able to see oil temperature, so I set-up a little dash with the oil temperature and, since there was space for more, I included boost pressure. Because why not.
After a trackday I was watching the max values logged, and the boost pressure seems a tad high: 2.28bar (33psi)
Initial assumption was that it is an absolute value (1bar + boost), but the display reads 0 or 0.01 when the car is idling.
Considering 33psi seems unrealistic on this engine... or at least unrealistic without blowing up the engine
Is the that data point from BimmerLink unrealiable? Or maybe that max figure is just a misreading (I have videos from inside the car, I'll check if I can read the figures during the sessions)?
Curiosity more than anything else... and a chance to learn a thing or two.
